Vipermetal unveil new 3D screening buckets

Vipermetal 3D screening buckets

Latest bucket attachments designed to increase productivity and improve quality of screened material 

VIPERMETAL (Ajutech Oy), Finnish specialists in crushing and screening buckets, have unveiled their new 3D screening buckets specially designed for use on excavators and loaders. The company has also announced their 4D screening bucket innovation is currently in development and being tested. 

Viper 3D screening buckets have been developed to allow reuse and separation of different materials and fragmentations, providing in-situation usage of otherwise waste materials. Trench filling and padding, topsoil mixing/stabilization and biomaterial screening/aerating are among the typical screening applications.


The Viper screening bucket attachment is designed to be lightweight and provide easy changeover of attachments between machinery. Downtime is, therefore, minimized, as one operator can do several jobs and a number of different attachments are used with the same base machine.

Viper 3D screening has been developed to increase hourly output and improve the quality of screened materials. Key benefits include:

  • Rotors located in the bottom of the bucket move the material forwards and backwards depending if the rotors are turned clockwise or anticlockwise
  • ‘CenterTwinSpiral’ rotors move material sideways; to the centre of the bucket and to the side of the bucket when rotating clockwise or anticlockwise
  • Optimally U-shaped rotating axles move the material up and down (rotating), resulting in improved screening quality and higher capacity especially when screening humid and sticky materials

All Viper screening buckets have anti-clogging to ensure effective screening and units are manufactured using only Hardox wear steel to eliminate dead weight, increasing capacity and reducing fuel costs.
